Using S/PDIF Auxiliary Output Mode
Hi, I am trying to use the S/PDIF Auxiliary Output Mode for a slightly unusual result. Basically I am trying to bypass the use of an ASRC... A customer has asked if our product can accept AES3 input W

SPDIF TX configuration and timing problems between chained devices
Hi Team, I have a custom made DSP board for a loudspeaker based on the ADAU1466 and currently having a problem with my S/PDIF signal chain. I run an ADC (@96khz) on SIDN1 through a ASRC2 into the DSP

SPDIF signal detection mechanism problem
Hi all, I have a problem with a S/PDIF signal detection mechanism on one of my ADAU1466 based DSP boards. The following screenshot shows the input routing of analogue inputs ASRC 2 & 3 and spdif left

AC3 or DTS Multichannel support on SPDIF
Hello, I would like to inquire whether the ADAU1452 supports multichannel audio transmission over SPDIF when encoded using AC3 or DTS formats. To provide some context, I am currently using the AD2428W

SPDIF RCA/Coax interface understanding
Hello EZ, Here I am with another question thats probably really stupid. I'm a mechanical engineer deeping my toes in audio electronics so please bear with me. I have sucesfully designed a PCB that is

Sending I2S from DSP to external DACs
Hi, I am trying to send I2S signal from DSP to external PCM1794 DACs. MCLK is sent out correctly from CLKOUT at 24.576MHz, but nothing else is getting out from serial outputs. What am I missing? Signa

ADAU1452 SPDIFIN pin voltage level(s)
Hi, can anyone point me to where there is a specification for the acceptable voltage levels on the SPDIFIN pin of an ADAU1452 DSP device? The only thing I can find in the data-sheet is on page 11 wher

DTS signal enters adau1452 through SPDIF without signal input
Hi: Input audio signal to ADAU1452 via SPDIF. If the input audio format is ordinary mp3, ADAU1452 has signal output, But if the input audio format is DTS, ADAU1452 has no signal output. Is there a way

ADAU1452 SPDIF Out Bitrate
Hi Is there any possibility on the ADAU1452 to use a sample rate other than the system sampling rate for the SPDIF ouput? For example can I use 192kHz as system sampling rate and set the SPDIF sample
-
ADAU1452 sampling frequency
Hi, I use an ADAU1452 to EQ a few subwoofers, and noticed the filters were not working properly (ie. PEQ was not affecting the signal in any way!) I realized I was setting the sample rate only in samp

ADAU1701 spdif to dolby/dts 5.1 output
Hello everyone! Please tell me how I can connect the spdif input to the ADAU1701? Is it possible? How can I decode the data received from the spdif input using dolby/dts 5.1 and feed it to the output?

ADAU1452 - Working at fixed sample rate
Hi, I'm using custom ADAU1452 board only for S/PDIF audio processing. In SigmaStudio, "START PULSE" is set to "S/PDIF receiver rate". ASRC0 output rate is set to "Use DSP core START_PULSE rate". For t

Sync SPDIF Tx rate to SPDIF Rx rate
Hi I similar question was on a post of the same "Subject" name https://ez.analog.com/dsp/sigmadsp/f/q-a/65396/sync-spdif-tx-rate-to-spdif-rx-rate Using the ADAU1452. The DSP is Locked to an external I

ADAU1452 -> ADAU1462 ASRC and 192kHz SPDIF
I have a product that has been in the market for several years now using the ADAU1452. It's only limiting factor for us right now is that the SPDIF input on that part maxes out at 96khz and we have ma

ADAU1462: loud pop/click when audio starts
Just completed a board that uses the ADAU1462to read audio through the S/PDIF optical input. The design closely follows the ADAU1466 evaluation board, with a self-boot EEPROM (which I successfully pro

Accessing SPDIF/I2S raw data
I'm using a ADAU144x eval board to convert an SPDIF input to an I2S output. The SPDIF input is a proprietary format with 3 data channels, each with left and right subframes. The data in each subframe

ADAU1442 SPDIF output sample rate error
Hi I have a ADAU1442 running as a slave to serial input 4 clock domain4 (TDM16) from another DSP IC(Master) The ADAU1442 is running external XTALin from the master DSP at 24.576 mhz (not from xtal) Th

Adding TOSLINK / optical input to 1701 project?
I have an older design using an ADAU1701, and we'd like to upgrade it to include consumer-grade TOSLINK (optical input), but I don't want to add too much cost. From my reading, this gets complicated,

ADAU1701 + S/PDIF in + I2Sin/out+ internal ADC/DAC + external DAC
Hi there, we are planning a small DSP board using the ADAU1701. Features should be: internal ADC (2 channel) internal DAC (4 channel) external S/PDIF receiver (maybe with transmitter to) external DAC

ADAU1452 SPDIF Input issue
Hi, I've built a custom PCB with ADAU1452 and everything is working quite well except for the SPDIF input. I think I've configured everything the way it should be, but no audio can be heard. My curren

ADAU1442 ASRC Implementation
Hello Everybody! My proposed design involves an ASRC in which the Sigma DSP accepts S/PDIF input signals at different sampling rates and output as a S/PDIF signal as well. Say for example, incoming si

Stable SPDIF I/O at 44.1kHz on EVAL-ADAU1452MINIZ EVM?
I am measuring the SPDIF I/O performance of the ADAU1452MINIZ EVM. My measurement system can record the exact output (with delay) when using SPDIF loopback at 44.1 and 48kHz. I set up the EVM (with Si
